Thirty years ago, he was set up by someone, accidentally killed and imprisoned. After twenty years of torture, his family was ruined after he was released from prison, and he finally died with hatred. Unexpectedly reborn on the night when he was stabbed in the kidney, he relied on his past life memories and hyperamnesia to kill the assailant and fabricate evidence to avoid the crisis. After his rebirth, he faced oppression and misunderstanding from all forces in prison and after his release. He not only had to survive in a harsh environment, but also had to rely on his own wisdom and experience to break through numerous obstacles within a limited time, expose anti-drug, counter-intelligence and other shady stories, and choose between adhering to justice and struggling to survive. As the investigation deepens, the mastermind behind the scenes becomes powerful. He cleverly guides the enemies to fight among themselves, and finally clears the grievances and completes the redemption from the abyss to the light.
